Unfortunately, I don't quite understand what you try to ask. However, for an example of how to build a custom service, I'd recommend you to have a look at nAN-36 . 
 We don't have any similar document explaining how to build a GATT Client, but there are some examples in the SDK, mainly ble_ias_c.c and ble_ans_c.c.
